I’m always adding `gem 'mysql2'` to the `Gemfile` which always seems to work, so I didn’t even notice that there is a problem.  
I guess I should read more about how Ruby handles its dependencies. Just to clarify, moving the `require 'mysql2'` to the top isn’t enough, is it? At least in my development environment I still get an error. So, how do I install the mysql gem without adding it to the `Gemfile` in order to make a simple `require 'mysql2'` work?
